Specification of Letters Patent.

ALARM DEVICE.

Patented Apr. 4, 1911.

To all whom it may concern.

Be it known that I, VALENTINE J. Nimm, a. citizen of the United Statesof America, residing at Pittsburg, in the county of Allegheny and Stateof Pennsylvania, have invented certain new and useful Improvements inAlarm Devices, of which the following is a specification, referencebeing had therein to the accompanying drawing.

This invention relates to an alarm device, and the primary object of myinvention is to provide a device for producing an audible signal at apredescribed time, somewhat similar to the ordinary and well-known typeof alarm clock.

Another object of this invention is to provide a portable alarm devicethat can be attached to an ordinary clock and actuated by the movementof the hour-hand for producing an audible signal.

A further object of this invention is to provide an alarm device thatcan be advantageously used by travelers in lieu of the present type ofalarm clock, the device being portable in connection with the ordinaryelectric alarm or bell circuit of a residence or hotel, or in connectionwith an electric circuit provided by a small dry battery.

A still further object of this invent-ion is to provide an alarm devicethat can be easily and quickly attached to the face of an ordinaryclock, to be actuated by one of the hands thereof at a predescribed timedetermined by the position of a portion of the device upon the face ofthe clock.

A still further object of the invention is to accomplish the aboveresults by a mechanical construction that is simple, durable, easilyinstalled, and highly eiiicient for the purposes for which it isintended.

With these and such other objects in view as may hereinafter appear, theinvention consists of the novel construction, combination, andarrangement of parts to be hereinafter specifically described and thenclaimed.

Reference will now be had to the drawing forming a part of thisspecification, wherein there is illustrated a preferred embodiment ofthe invention, but it is to be understood that the structural elementsthereof can be varied or changed without departing from the spirit andscope of the invention.

In the drawings: Figure 1 is a front elevation of the dial of a clock,Showing my device attached thereto. Fig. 2 is an enlarged verticalsectional view of the device showing it connected to a bell and suitablesource of electrical energy. Fig. 3 is a front elevation of the device.Fig. 4 is a cross sectional view of aI portion of the same.

In the accompanying' drawings the reference numeral 1 denotes a suctiondisk preferably made of rubber or other flexible and resilientinsulating material capable of being mounted upon a surface by crea-tinga vacuum between the disk and the surface. r)The disk adjacent to theedge thereof is pro` vided with a bearing plate 2 for a resilientcontract arm 3, said arm of the plate 2 being retained in engagementwith the disk 1 by screws 41 or other fastening means, one of the screwsbeing provided with a binding post 5. The opposite edge of the diskl isprovided with a contact plate 6 and adapted to engage said plate is acontact block 7 carried by the free end of the arm Mounted upon the disk1 intermediate the plates 2 and 6 is a plate 8 said plate being securedin position by rivets 9 or other fastening means. The plate 8 isprovided with diainetrically opposed bearings 10 supporting a movableshaft 11 and upon said shaft are mounted a projection 12 and atrip-lever 13. The projection 12 is adapted to extend upwardly under thearm 3 and hold the same in an elevated position, while the triplever 13extends upwardly upon one side of the arin 3, for a purpose that willpresently appear.

The binding post 5 is connected by a wire 141 to al suitable source ofelectrical energy 15, as a dry cell battery, and this battery isconnected by a wire 16 to an electric bell 17, said bell being connectedby a wire 18 to the contact plate 6. The wire 18 is adapted to extendthrough the side wall of the disk 1 and then through the body of saiddisk and connect with the plate 6.

The application of the alarm device to a clock is shown in Fig. 1 of thedrawings, where it will be observed that the vacuum or suction disk lhas been secured to the dial 19 of the clock and in position to have thetrip-lever 13 thereof impinged by the hourhand 20 of the clock. With thehour-hand 20 located beneath the minute-hand 21, the minute-hand canfreely travel over the face of the clock without actuating the device,but immediately upon the hour-hand 20 impinginjbY the trip-lever 13, theprojection l2 Will release the resilient arin 3 and allow the bleek 7 toengage the Contact plate G, and thereby establish a circuit through thesource of electrical energy l5 and the bell 17, to sound an audiblesignal until the device is removed from the dial of the oloek, or if adry eell battery is used, until the cell is exhausted.

From the foregoing it Will be observed that have devised al simple alarmdevice in eonneetion ivith Whieh a very sin-all eleotrie bell andbattery can be used, and the disk secured to most any clock dial to beactuated at a pre-determined time. Such a device can be advantageouslyused by traveling salesmen, professional hunters and parties desiring torise in the early hours et the morning Wit-hout the services of acall-boy or another party.

I am aware that vacuum or suction disks have been used for otherpurposes, but believe that its use for supporting a Contact arm inconnection with an alarm has never been used before.

Having` now described my invention what l claim as new, is

ln an alarm device, the combination With an electrical circuit a belladapted to be operated thereby, of a suction disk, and a resili entContact arm carried by said disk and adapted to establish a Circuit'through said bell.

ln testimony whereof l atli; my signature in the Apresence of tivoWitnesses.
